county of Jefferson and State of Texas, have invented certainnew and useful Improvement in Stills, of which the following is a specification. 7

This invention relates to new and useful improvements in a still, and particularly in a still designed to be used for distilling petroleum or its products.

The object of the invention is to provide a still of the character described for removing water and the volatile constituents from heavy crude oil, in the manufacture of refined oil or in the preparation of said constituents for distillation in the ord1 nary manner. The type of still hereinafter described will bring the oil into contact with auniform heat and provides for the relief of any suddenly formed vapors, whlch would cause the oil to boil over in stills now in common use.

With the above and other objects in View, the invention has particular relation to certain novel features of construction, operatioh and arrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, wherein:

Figure 1, is a vertical sectional view ot the still.

Fig, 2, is a transverse sectional view, Show ing the feeding coil employed, and,

Figs. 3 and 4, show plan views of the transverse plates or partitions employed.

Referring how more particularly to the drawings, wherein like numerals of reierence designate similar parts in each of the figures, the numeral 1, refers to a cyllndrical casing, preferably formed of sheet metal which is surrounded by a covering 2, formed of asbestos or some similar material, provided for the purpose of retaining the heat.

and guarding against sudden changes of temperature, and the casing is provided with a dome 3, having diaphragms, as 1, pro ecting" inwardly from opposite sides thereof and whose tree edges overlap, so as to revent the fluid spray from being carried into the vapor line 5, which is controlled hy the valve .6, and which leads to a suitahlecondenser, not shown).

ll. "col 2 whose under side is provided with a double row of perforations 8, is arranged in the upper portion of the still and communicates with the inlet pipe 9, which is controlled by the valve 10, and which leads from the suitable feed tank or pump. A steam line 11, controlled by the valve 12 enters the still near the bottom and terminates in a coil 13, within the still, the upper side of said coil being provided with a double row of perforations. The steam line 11, is connected with a suitable super-heater, (not shown). Leading from the bottom of the still is the discharge pipell, controlled by the valve 15, and through which residual oil is discharged from the still into a suitable receiving tank, (not shown), and a drain pipe 16, controlled by the valve 17, also leads from the bottom of the still, through which surplus water, formed in the still while heating up preparatory to distillation proper, may be drained 0d.

Between the coils 7 and 13, and secured to the casing wall is a series of projections 18, which are fixed to said wall and are spaced a uniform distance apart there.

around, the projections at each series heing 1n transverse allnement and the ser1es bemg spaced the required distance apartvertically.

Each series of projections supports a transverse plate or partition, as 19, and 20. These partitions are perforated, the partitions 19, having annular rows or perforations, as 21, out near the edge, and the central portion of the partitions 20, having the perforations 22, the perforations of each plate being out of vertical alinement with those of the immediately succeeding plates above and below, so that the su erheated steam delivered through the coil 13, will pass u in a devious course through the series o partitions. The partitions have peripheral notches, as 23, and in placing any particular partition in position on an articular series of projections 18, the partition is turned, so that the projections alcove said series will pass throughsaid notches and mid partition is then turned, so as to rest upon the desired projection as shown in Fig. 3, to which it is secured and, the notches are then closed by meansof plates, as 24, which are secured to the partition, as is also shown in Fig. 3.

The oil to he treated is admitted through the pipe 9, 5 opening the valve 10, out not unt1 after t e still has been heated "by the admission out super-heated steam from the coil 13, and the condensed water which may have formed has been drained off through the pipe 16.

A. steady stream of oil is kept running through the coil 7, the valve 6, beingpartially closed, so as to "create a slight pressure in the still. The oil will gradually trickle down through the perforated partitions 19 and 20, andwill be heated by the steam passing upwardly therethrough and the volatile portion will be separated from the residual oil and will pass up through the domeand out through the line 5, to the condenser. lhe amount of residual oil which collects in the bottom of the still, will be indicated by the glass gage 25, and the amount of pressure in the still Willhe indicated by the pressure gage 26. When the residual oil hegins'to show in the gage 25, it may be drawn 05 through the discharge pipe 14, Leading from the side of the still between the partitions 19 and. 20, are the gage cocks 27, by means of which the condition of the oil in the still may be ascertained and near the bottom of the still is thermometer 28, to indicate the degree of heat of the oil within the still.

I have shown only one form of this device, but it is obvious that the mechanical structure thereof may be Varied Without departatina? sirable so long as I keep within the scope of the appended claim.

What I claim is: A device of the character described including a receptacle having a dome, a coiled 1 nozzle provided with a plurality of dis-- charge perforations arranged at the top and bottom respectively, of the receptacle, oil

apart and dividing the receptacle into separate compartments, some of said partitions having a plurality of central perforations and the others having a plurality of marginal perforations arranged in annular rows, the first mentioned alternating with those last mentioned, gage cocks communicating with the respective compartments be tween said partitions, diaphragms projecting inw rdly from opposite sides of the dome an arranged in staggered relation, a vapor line leading from said dome and a discharge pipe and a drain pipe leading from the bottom thereof.

In testimony whereof I-have signed my name to this specification in the presence of two subscribing witnesses;

BENJAMIN enhnswonrnr.
